There are two main aims in applications of PTLC in organic geochemistry (1) assessment of the bulk group composition of soluble organic matter by its fractionation and (2) separation of a particular selected group of compounds with geochemical meaning. The important factor in technique selection should be the repeatability of...

Humin has been regarded as the most intractable component of SOM. It must be considered to be a very important component, however, because typically it represents more than 50% of the organic carbon in a soil (Kononova, 1966 Stevenson, 1982,1994) and more than 70% of the organic carbon in unlithified sediments (Durand and Nicaise, 1980 Rice, 2001). The definition of humin (Section 1.3.3) is similar to that of a protokerogen (Calvin and Philip, 1976 Rice, 2001), which is often used in petroleum geochemistry to describe insoluble organic matter in unlithified sediments.
